Disable Submit Button Upon Form Submission
Multiple clicks on a "Submit" button can cause duplicate processing if your programming is slow or the user's connection is lagging. Duplicate processing can include duplicate database records, multiple emails, or different types of errors. JavaScript provides an easy way to disable the multiple submission of a form once the form has been submitted.
The Code
In the HTML, use the following "onsubmit" information:
It's important to trigger the even on form submission -- not everyone clicks the "submit" button. You will also need to give your submit button the submit_button ID attribute.
Client-side APIs on mobile and desktop devices are quickly providing the same APIs. Of course our mobile devices got access to some of these APIs first, but those APIs are slowly making their way to the desktop. One of those APIs is the getUserMedia API...
While synchronous code is easier to follow and debug, async is generally better for performance and flexibility. Why "hold up the show" when you can trigger numerous requests at once and then handle them when each is ready? Promises are becoming a big part of the JavaScript world...
Before you send your user to an unknown external website, why not provide them a screenshot of the site via a tooltip so they may preview the upcoming page? Here's how you can do just that using MooTools.

Last year I wrote a popular post titled AJAX For Evil: Spyjax when I described a technique called "Spyjax":
Spyjax, as I know it, is taking information from the user's computer for your own use — specifically their browsing habits. By using CSS and JavaScript, I...
As an aside, if you’re also using any javascript validation, disable the submit button only after you’ve passed the validation tests.
Also, if the form is output programattically and the results stored in a DB, you can incorporated a unique hidden value in the form and redirect to an error page on duplicate submission detection.
Great tips (and name) Dave!
I’ve never been a fan of “disabling” elements on a website, but if it can save a developer lots of cleanup in the long run, I say do it.
How would you write a code to “redirect to an error page on duplicate submission detection.”
oh, and my middle name is David. It may not be Dave but it is pretty close. :D
thanks for the tip… might also be a good idea to apply some sort of visual display so your users know the server is working. :)
Hi David,
I’m having a really hard time trying to disable a submit (IMAGE) button when the page is submitted in APEX 3.2.
I cannot get the SUBMIT button to disable itself. Somehow this only works on HTML Buttons rather than IMAGES from CSS Templates.
Would appreciate it if you could suggest an alternative.
Thanks.
Great way of prevention. Thanks a lot. I just implemented it on one of my websites.
Does anyone have a unit test code for testing the submit button disabled when click it?
Thank boss..u saved my time
